how we can improve power factor from 0.8 to 0.85 or 0.9 &
how we identify its either lag or lead ? thank you
Answer Posted / hit_dav
By putting Automatic power factor correction panel which
has the capacitors in steps as per load requirement for
improving power factor & with relay for identifying whether
it is leading or lagging.For that first of all we need to
understand our load(KW) conditions then we can calculate
how much capacitors in KVAR we required.
